Asteraceae herb for Identification : AVD10122017:01 : 13 posts by 4 authors. Attachments (6)

I need help in identifying the Asteraceae herb in images attached herewith. The detailed description is as follows:
A stout herb 1 to 2 meter high, stem 5 angled, deeply grooved, star shaped in cross-section, leaves alternate, sessile, linear ob-lanceolate, cuneate, sharply dentate, flower heads in corymbs, peduncles bracteolate, florets lavender in colour. Involucral bracts striated with green and white lines.
Am unable to place it in appropriate genus. Would kindly request for help.


Closure to Emilia sps.


Thank you for suggesting possible id. But the involucral bracts are completely different from Emilia.
The possible id is Goniocaulon glabrum


i have also come across same plant and i am of the opinion that it is Vernonia spp but not sure about spp

i will post my images soon 


Pl. check with 

/species/a—l/ar/asteraceae/cichorioideae/vernonieae/cyanthillium/cyanthillium-cinereum

It is a highly variable species. 


The species is quite different from the link sent by you. The distinctly grooved angular stem, shorter peduncle, and most importantly paleaceous pappus are not seen in the linked images.
Please check the following link. The herbarium specimen shows all features similar to my plant specimen.

Adding few more images of flower head, floret and achene.

This is to aid id confirmation.

… as … pointed out this spp is highly variable, flower shape of plants growing in crowded area have different shape and other have different, unfortunately my computer is having some problems so i will post my images afterwards


Thanks, …, for the new addition.
I also agree with your id of Goniocaulon indicum (Klein ex Willd.) Benth ex C.B.Clarke (syn: Goniocaulon glabrum Cass.) as per high resolution specimen & details as below:
